CCDCONFIG(8) NetBSD System Manager's Manual CCDCONFIG(8)
NAMEccdconfig -- configuration utility for the concatenated disk driver
SYNOPSISccdconfig [-cv] ccd ileave [flags] dev [...]
ccdconfig -C [-v] [-fconfig_file]
ccdconfig -u [-v] ccd [...]
ccdconfig -U [-v] [-fconfig_file]
ccdconfig -g [-Mcore] [-Nsystem] [ccd [...]]
DESCRIPTIONccdconfig is used to dynamically configure and unconfigure concatenated
disk devices, or ccds. For more information about the ccd, see ccd(4).
The options are as follows:
-c Configure a ccd. This is the default behavior of ccdconfig.
-C Configure all ccd devices listed in the ccd configuration file.
-fconfig_file
When configuring or unconfiguring all devices, read the file
config_file instead of the default /etc/ccd.conf.
-g Dump the current ccd configuration in a format suitable for use
as the ccd configuration file. If no arguments are specified,
every configured ccd is dumped. Otherwise, the configuration of
each listed ccd is dumped.
-Mcore
Extract values associated with the name list from core instead of
the default /dev/mem.
-Nsystem
Extract the name list from system instead of the default /netbsd.
-u Unconfigure a ccd.
-U Unconfigure all ccd devices listed the ccd configuration file.
-v Causes ccdconfig to be verbose.
A ccd is described on the command line and in the ccd configuration file
by the name of the ccd, the interleave factor, the ccd configuration
flags, and a list of one or more devices. The flags may be represented
as a decimal number, a hexadecimal number, a comma-separated list of
strings, or the word ``none''. The flags are as follows:
Symbolic Numeric Comment
CCDF_UNIFORM 0x02 Use uniform interleave. The size of all
components is clamped to that of the
smallest component.
CCDF_NOLABEL 0x04 Ignore raw disklabel. Useful when creat-
ing a new ccd.
/etc/ccd.conf
The file /etc/ccd.conf is used to configure ccdconfig if -C or -U is
used. Each line of the configuration file contains arguments as per the
-c argument: ccd ileave [flags] dev [...]
A `#' is a comment, and everything to end of line is ignored. A `\' at
the end of a line indicates that the next line should be concatenated
with the current. A `\' preceding any character (other than the end of
line) prevents that character's special meaning from taking effect.
See EXAMPLES for an example of /etc/ccd.conf.
FILES
/etc/ccd.conf - default ccd configuration file.
EXAMPLES
The following command, executed from the command line, would configure
ccd0 with 4 components (/dev/sd2e, /dev/sd3e, /dev/sd4e, /dev/sd5e), and
an interleave factor of 32 blocks.
# ccdconfig ccd0 32 0 /dev/sd2e /dev/sd3e /dev/sd4e /dev/sd5e
An example /etc/ccd.conf:
#
# /etc/ccd.conf
# Configuration file for concatenated disk devices
#
# ccd ileave flags component devices
ccd0 16 none /dev/sd2e /dev/sd3e
